Barrett was educated at the University of Reading[1] and the University of California, Berkeley where he was awarded a PhD in 1977[3][9] for research into the breeding systems of the plants Eichhornia and Pontederia supervised by Herbert Baker.[4]

Research and careerEdit

Barrett's interests are in evolutionary biology, evolutionary genetics, evolutionary ecology and plant reproduction.[2] His research seeks understanding how flowers evolve and what mechanisms are responsible for mating system transitions in flowering plants.[10] As of 2017 he is the editor of the Proceedings of the Royal Society series B,[11] the flagship scientific journal of the Royal Society.

Barrett is an evolutionary biologist and a worldwide authority on the ecology and genetics of plant reproduction. His work has focused on increasing our understanding of how flowers evolve and the mechanisms responsible for mating system transitions in flowering plants.

Through innovative experiments, amongst his other discoveries, Spencer provided the first experimental evidence for the purging of deleterious genes following inbreeding in plants. He also demonstrated that self-fertilisation owing to large floral displays in plants has a detrimental effect on the male fertility of plants.

Spencer’s research group at the University of Toronto focuses on understanding the mechanisms responsible for the evolution of plant mating strategies, and he has edited several leading books in the field.

Awards and honoursEdit

Barrett was elected a Fellow of the Royal Society of Canada in 1998 and a Fellow of the Royal Society of London in 2004.[10] He was awarded the Sewall Wright Award by the American Society of Naturalists in 2008 and was President of the Canadian Society for Ecology and Evolution from 2010 to 2011.[10]

He received the Sewall Wright Award from the American Society of Naturalists in 2008 and was President of the Canadian Society for Ecology and Evolution from 2010–2011.[10] In 2014, he received the Flavelle Medal from the Royal Society of Canada.[12]
